Guest Posted May 8, 2015 Report Share Posted May 8, 2015 About the Keynesian curve, is it an AS curve or a LRAS curve. In the oxford book they use both AS and LRAS whereas in the cambridge textbook it says the keynesian curve is a short run curve. Additionally, the vertical line in the Keynesian curve is not the same as the potential output right? It should be the maximum output of the country when it employs all the resources in the economy, no natural unemployment.but potential output is with natural unemployment.In the oxford book, they say the vertical line is just the full potential, but in other textbooks, pearson and cambridge, they say it is not the full potential and it exceeds the full potential. I am confused. Reply Link to post Share on other sites More sharing options...

I am confused.Keynesian curve is the same curve in both SRAS and LRAS. The vertical curve should be the potential maximum output in a country keeping natural unemployment in mind. It does employ all resources at the vertical line yes, but there is still natural unemployment because there will always be natural unemployment present, it is not possible to get rid of it, decreasing is to some extent possible though.

Hope this helped But in the some textbooks, they say the vertical line involves no natural unemployment and is not the same as the potential output. so I dont know what to trust. And what should I label the curve? I mean should I label LRAS or SRAS or keynsian AS? Reply Link to post Share on other sites More sharing options...

And what should I label the curve? I mean should I label LRAS or SRAS or keynsian AS? Can't tell you what to trust, but I have learned it that way at least. If you have a new-classical LRAS curve and a Keynesian AS curve in the same test paper I would label them differently to indicate that one is the new-classical LRAS curve and the other the Keynesian AS curve Reply Link to post Share on other sites More sharing options...
EconDaddy Posted May 9, 2015 Report Share Posted May 9, 2015 Hi, I'm glad that you have the pearson book, Lovelife. Let's make things clear. The Keynesian AS curve is what we call the SRAS curve, as it usually works in the short-run. It is not the same as LRAS. The monetarist AS curve is the (vertical) LRAS and this shows the potential output at the full employment level. The reason why we use two AS curves is to show that changes in AD will most usually have effects on real GDP only in the short-run, whereas in the long-run it will mostly influence the average price levels, but not the output. This is mainly due to the sticky wages. While operating at the full employment level of output, the economy still experiences frictional, seasonal and structural unemployment, all of which are part of the natural rate of unemployment. So Lynxsarin was right here. Have a look at p.296 for the natural rate of U in the pearson book. Hope this helped clear any doubts.
